PAPER-FEEDING. MACHINE.

To all inkom, it may concern:

Beit known that'I, RICHARD E. JoNEs, a

citizen of the United. States, and a resident of Pearl River, in thencounty of- Rockland and State of New York, have Ainvented certain new and useful Improvements in Paper- Feeding Machines, of which the following 1b granted .15 ithe sheets, the clutch is retained in active position, but is in readiness to operateper1od1-- -is a full and clear s ecication.

In the atent of exter et al., No. 779,914, anuary 10th, 1905, is disclosed a sheet calipering device for paper feeding machines in which the operation of the feeding machine is thrown out bythe attempted passage of an extra. thickness of sheets from pile. In this atented', mechanism -a clutch o rating roc `shaft'is controlled by a suitable cam and the sheet actuatedcalipering device so that in the normal operation ofthe machine in passing successivesmgle cally inthe event of the detection bythe calipering device of an extra thickness of sheets. The mechanism of this p atent has .25 gone largely into use and has given considerable satisfaction 1n accomplishing the results aimed at, but it has been found from practice that while the mechanism will arrest the operation of the machine under the control of the calipering device, the momentum or raclng of the machine at the time the clutch is thrown out, is frequently sulficient to carry forward the objectionable extra thickness of sheets onto the conveyer before the machine is actually stopped, so as to require considerable time and trouble in removing the improperly fed sheets before the feeding operation can be resumed.

With this objection in view, the present invention may be considered as an improve- A understood I Wi -ings and afterward point out the noveltyr ment upon the structure' of the above namedpatent, and to this end the present invention consists of combining with a sheet caliperingcontrolling device of the type referred 45 to, suitable means for automatically preventing the action of the drop roller sheet 'delivery mechanism when theinachine is thrown out bythesheet calipering device.

lIn order thaty invention may be -fully lil iirst describe the same with reference to the accompanying drawmore particularly in the annexed claims,

In said drawings Figure l is a vertical longitudinal sectional elevation of part of Specification of Letters Patent. Patented Iay 20, 1913, application aieuanuary 24, 1912. semi im. 673,21.

a paper feeding machine embodying the present invention and showing in' full and dotted lines the\cliangc.in positions of the parts during the normal operation of the machine. Fig. 2 is a similar view illustrating in full and dotted lines the change in position of the parts when the machine is thrown out by the automatic acti-on of the -present invention. Fig. 3 is a detail front elevation of the parts shown in Figs. 1 and 2. I have shown in the drawings only enough of the Well-known automatic paper feeding machine Vto illustrate the action of the present invention. A

-1 represents part of the main frame of the paper feeding machine,l P, indicates a por'- tion vof the pile of sheets which are mounted upon the usual automatically elevated table or. platform.

10 is the cam vshaft or main operating shaft from which all of the partsof the paperfeeder are' driven in this type of machine. This shaft 10 is equipped with a suitable controlling clutch (not shown), such for exam le as illustrated in the patent of Dexter, Upon -the shaft l0 is mounted a clutch controlling cam 15 upon the periphery of which operates an anti-friction roller 16 freely journaled in the end of a rock arm 17 keyed to a transverse rock shaft 18 freely j ournaled in the side frames of the machine. This rock shaft 18 is a clutch operating or controlling shaft by which the main clutch of the feeder is thrown into and out of operation. this type of machines. by the rocking movement of the shaft such asj18 is so well known in the art that the mechanismby which the clutch is controlled is not illustrated in the accompanying drawin s. The rock arm 17 is formed with a latera ly projecting nose 20 which normally rests just above the upper end 53h1 of a caliper operated lever presently. to be eX lained.

30 is t e lower rotary member of the sheet calipering device mounted upon 'a trans.-

feeding machine beneath theplane of feed of the sheets. Thisjshaft 31 is the lower feed shaft which carries a plurality of lower feed rollers such as at 32 with which cooperate tlie drop lrollers indicated at 33 freely journaled upon the forward ends. of rock arms 34 projecting from a rockshaft o. 663,672 of'December 11, 1900.-

The controlling of theclutoh 'in verse vshaft 3l at the delivery end of the 35 journaled in the side frames of the machine and operated by the usual controlling cam mechanism .which is not shown.-

is the upper normally stationary rotatable calipering member shown 'in the form of a segment journaled at 41 upon a laterally projecting bearing member 42 of an angular bracket A43 which is pivotally mounted at 44'forwardly of the journal 41 referred to.' The bracket 43 is pivoted upon a rigid bracket arn'i 45 projecting inwardly from the side frame of the machine. The upper end of the bracket 43 is connected by a spring 4G with the bracket 45 and is adjusted upon its pivot 44 by means of an adjusting ,screw 47 threaded through the bracket 43 engaging a lug 48 projectmg laterally from bracket 45.

The'rotary ealipering segment or member 40 carries above its journal 41 a laterally projecting pin 50 which rests beneath the lower arm `51 of a lateral extension 52 of lever 53 which isA pivotally mounted at 54 upon an upper extension of bracket 45. This lever 53 has its upper end` 53a resting beneath the nose 20 as above referred to.

The mechanism so far as specifically described is essentially the same as illustrated in t-he above named Patent No. 779,914 and it will be understood by referring to said patent that the passage of an abnormal thickness of sheets between the calipering members 30 and 40 will rock the lever 53 either by the rotation of calipering member 40 or by the vertical yielding of bracket member 43 upon its pivot 44, thereby moving the end 53a from beneath the nose 20 to permit the rock arm 17 to fall when the anti-friction roller 16 reaches the low part so that the rock arm of the controlling cam 15. In addition to this result, my present invention includes means for preventing the continued operation of the drop roller delivery mechanism by the racing or momentum of the ma chinc. To accomplish this I mount upon the clutch operating rock shaft`18 an inwardly presented rock arm 60 and I mount upon the drop roller rock shaft 35 a long upwardly presented rock arm 65 whose upper end normally rests a little in front of and just beneath the forward end of said rock arm (30 as shown in full lines in Figs. 1 and 2. From this it will be observed that in the normal operation of the machine with the clutch operating rock shaft 18 held against motion by the controllingr cam 15 and caliperoperated lever 53 that the rock arm 65 upon rock shaft 35 will rock rearwardly beneath the rock arm G0 every time the droprollers 33 move into engagement with the sheet above the lower feed rollers 32. I'Vhcn, however, the caliper mechanism is actuated by an extra thickness of sheets 17 is released and the rock shaft 13 is rocked, the arm GO will fall suiciently to engage behind the upper end of rock arm 65 and thereby prevent the loweringof the drop rollers 33 into opera tive position. The normal working of the drop roller mechanism is illustrated in Fig. 1 and the arrested4 position of this mechanism is shown in dottedlines in Fig. 2. l

With this improved mechanism it willbe understood that the improper thickness of sheets cannot be carried past the delivery mechanism of the feeding machine so that it is a much simpler and quicker operation to replace the improper sheets and resume the normal operationA of the feeding machine.
